Claims. (Cl. -62) This invention relates to novel improvements in closure devices and has particular reference to that form of closure device generally recognized as jalousie windows, wherein a plurality of horizontally pivoted panels are mounted in a frame to simultaneously swing in a vertical plane from a full opening to a fully closed and overlapping relation with each other.

Most of the jalousie windows now in use, have a recognized common fault, which fault relates specifically to their inability to successfully exclude the entry of foreign matter, such as air and water and particularly water in the presence of excessive wind pressures.

An object of the present invention resides in forming a novel extruded frame having side jambs that are extruded to form weathering channels for their full height and novel end clips for the panels that are pivotally supported upon the jarnbs adjacent the channels and with the end clips provided with generally U-shaped channel members that have a weathering engagement within the jamb channels when the panels are shifted to the closed position.

A further object of the invention resides in the novel construction of the end clips and their pivotal support upon the jambs in a manner whereby exterior wind pressures serves to more firmly weather the panels, one with the other throughout their length and with the mounting likewise serving to more firmly weather the panels under" 4 the influence of interior vacuums created when windows are open upon the opposite side of the building.

A further object of the invention resides in the novel extruded side jambs in combination with the novel end clips whereby the several panels maybe partially or wholly opened and with the channel members of the clips lying relatively close to a forwardly extended wall of the jambs to effectively prevent unauthorized entry to the window opening by bending the clips outwardly to release the panels, this being also a common fault with well known jalousie Windows now in use.

Other objectsyand advantages reside in the details of construction and operation as more clearly hereinafter described and claimed, reference being had to the accompanying drawings forming a part thereof, wherein like characters of reference are employed to denote like parts throughout the several figures.

Referring specifically to the drawings, the numeral 5 designates side jambs, connected at their opposite ends by a header 6 and a sill 7, all preferably extruded from aluminum. The jambs 5, header 6 and sill 7 are shaped to provide a circumferential recess '8 for the flush seating of a conventional insect screen frame, not shown. The jambs 5, header 6 and sill 7 form a rigid frame for the support of a closure device, to be presently described. Each side jamb 5 is extruded to form offset walls 8 and 9, with the wall 8 terminating at a point to form a flange 10 that overlies an adjacent area of the wall in spaced relation thereto to provide a forwardly opening channel 11. The wall 8, flange 10 and wall 9 are parallel and extend for substantially the full height of the jambs. Outwardly directed and right angularly disposed flanges 12 are formed integral with the jambs and provide the mounting means for the frame within the window opening of a wall or precast concrete open frame. The flanges 12 form the base for the channels 11, as clearly shown. The walls 9 extend forwardly of the channels 11 for a predetermined distance and with the overall widths of the walls 8 and 9 being proportioned to dispose the frame in the conventional precast concrete frame. The header 6 and sill '7 are provided with flexible weather strips 13 and 14 respectively, to have a weathering engagement with upper and lower panels and their respective end clips, to be presently described.

The window of the present invention comprises a plurality of flat elongated panels 15, here illustrated as glass, that are supported within the window opening of the extruded frame by pivotally connected end clips, designated as a whole by the numeral 16. Wood or other types of panels may obviously be substituted for the glass panels 15.

Each of the end clips, to facilitate their manufacture, are stamped, cast or otherwise formed and are preferably, although not necessarily formed in two parts, with each clip comprises a weathering channel member 17 and a panel supporting member 18. The channel member 17 is stamped or extruded, preferably from aluminum and includes a pair of flat and spaced apart parallel flanges 19 and 20. One end of the flange 20 is bent outwardly and upwardly to form a parallel car 21, that is apertured at 22 for the passage of a stud or other pivotal support means 23. The flange 20 is further provided with an integral rearwardly extending and upwardly angled crank arm 24, that is offset at 25 to dispose the crank arm closely adjacent the inner surface of the wall section 8, in use. The panel supporting member 18 is of general channel form and embodies a base wall 26, an outer right angle flange 27 and an inner right angle flange 28. The flanges 27 and 2.51% are parallel and spaced apart as shown. The flange 27 at its lower end is bent to form a panelstop and weathering tongue 29. The flange 28, adjacent its lower end, is provided with an inwardly directed spring tongue 30 for yieldable engagement with the inner surface of the panel, while the opposite end of the flange 23 is split and angled upwardly and then extended to form a spring tongue 31 for yieldable engagement with the inner surface of the panel adjacent its upper marginal edge. The extended portion of the tongue 31 is bent at a right angle to form a panel stop 32. The base wall 26 is further cut away at its opposite ends, as at 33, to facilitate the overlapping and interlocking of the opposite ends of the adjacent end clips when the window is in the closed position. The flange and the base wall 26 are apertured at spaced apart points and with the apertures being in registry when the clip is assembled. Rivets 34 or other fastening means are employed to rigidly connect the members 17 and 18 together. As clearly shown, the members 18 are angled with respect to the base wall of the channel j nel 11 for substantially its full length. Thelower end'of the base wall of the channel member 17 is extended at 35; to have an overlapping weathering engagement with the upper end of the base wall of the next adjacent channel member 17 when'the window is in the fully closed position. several panels are shifted to the fully closed and "over lapping position of Figure 1, the flanges of the several end clips, shown at 19, will have a weathering engage ment within the channels 11, the base Walls of the chan' nel members 17 will have a weathering engagement with each other through themedium of the extendedends 35 and the weathering stops 29 ofeach flange 27 have an overlapping and weathering engagement-with their adjacent flanges 27. Thus, a very effective weather seal has been provided between the several clips and between the several clips and the jambs. The upper and lower panel It will thus be clearly apparent, that when the the panel to be forced into the channel of the member 18 to a pointwhe're its outer marginal edge overrides the spring tongue and abuts the stop 29, at which point the inner marginal edge of the panel has shifted past the stop 32 and may be dropped into contacting engagement with the tongues 31. The tongues 30 and 31 firmly bind the panel against the flange 27 for a weathering engagement, while the stops 29 and 32 prevent endwise shifting of the panel with respect to the clip. Thus, the panel is easily installed within the clips without the necessity of employing bendable stops. After the several panels have been installed, the window is ready for operation in the usual manner. It should be here pointed out, that the offsetting of the ears 21 and the crank arms 24, place these elements in an operative position that provides adequate clearance for the installation or removal of the panels. The panels may be readily removed from their clips, by flexing the tongues 31 downwardly until the stops 32 clear the marginal edge of the panel. The particular angularity of the crank arms 24 and the 'pivotal support of the end clips at their upper ends, permits the shifting of the panels through a wide range from a fully closed position to a fully opened position where the panels are angled upwardly, thus greatly enhancing the circulation of air to the building.

Jalousie windows heretofore used are objectionable in that, when the panels are in the open position, the end Tclips," usually formed of relatively soft'metal, such as members and their associated end clips have a weathering contact withthe flexible weather strips 13 and 14. The window is thus most effectively sealed against the entry of water past the pivotally supported panels.

It is particularly desirable that the end clips shall be pivotally supported at their upper ends, since such a support imparts a very considerable closing leverage for the panels. Thus, in the presence of wind and wind driven rain, the pressure exerted against the outer surface of the panels will have a multiplied closing leverage that causes 1 the overlapping edges of the panels to more firmly engage and create a most effective seal throughout their length.

With the window in the fully closed position, as'in' Fig-- ures 5 and 6, it will be seen that the base wall of the channel member 17 and its flange 19, areslightly spaced from aluminum, are unsupported for their major length and has permitted unauthorized persons to easily bend or flex the end clips laterally to release the panels and thereby gain access 'tothe window opening. The channel members 17 and 18, due to their peculiar channel formation, arenot easily bent or distorted and, as clearly shown in Figure 4, with the window in the open position, any attempts at bending or flexing the end clips laterally will be retarded by the engagement of the channel member 17 against the surface of the extended wall 9'of the jambs.

the flange 10, thus assuring that the panels 15 may have adequate closing and contacting engagement. The pivots 23 are preferably headed and shouldered studs that have either a threaded or a riveted engagement within openings formed in the flanges 10, but with the ends of the pivots 23 terminating substantially flushwith the inner surface of the flanges 10 to offer no interference with the freedom of weathering engagement of the flanges 19.

Each crank arm'24 is apertured adjacent its outer-end,

as at 24', for pivotal connection with common operating a The oper bars 36 in the usual and well known manner. ating bars 36 are shiftable in a vertical plane under the influence of links 37 and 38, with the link -38 being fast upon and controlled by any well known type of geared operator 39. e

The use of the'device is as follows: 7

It being assumed thatthe several end clips have been fully assembled by'their rivets 34, the several clipsare then pivotally mounted upon the jambs through the medium of their pivotal studs 23.; The several crank arms 24 at each side of the-window are then connected to their respective operating bars 36- and the links 37 and 38 connected to the lower ends of the bars. The operator then simultaneously shifts the several clips outwardly for disposing them in substantially a horizontal plane. ;The panels having been previously cutj'to the desired length, the operatorengages the opposite ends of a panel'beneath theupper'end of the flanges 27 and against: the stops 32. Then, by forcing the panel downwardly against the stops 32, cause the tongues 31 to flexjdownwardl'y and permit Thus, unauthorized entry will be largely discouraged.

It will be apparent from the foregoing, that a very novel form of closure device has been provided. The novel side jambs' with their weathering channels and the novel end clips that have weathering engagement with the channels and weathering engagement with each other provides a distinct improvement in the art. The end clips may be stamped and assembled at a minimum cost and provides amounting support for the ends of the panels which is extremely strong. The panels may-be installed with a minimum of effort and requires no tools or separate fastening device and securely supports the panels against rattling or shifting. The pivotal support for the end clips further impart an exceptional closing leverage'and insures that the stronger the wind pressures, the tighter the weathering overlap will be.

'The'illustration of the end clips, wherein they are formed in two parts and welded, riveted or otherwise fixed together into a substantially unitary structure, discloses but'one method of manufacture and, it will be apparent to anyone skilled in the art, that these clips may be die cast or otherwise formed as an integral-unit.

While a preferred embodiment of the device has been shown, it is to be understood that changes in the shape, size and arrangement of parts may be resorted to as readily fall within the spirit of the invention or the scope of the subjoined claims.
